GNSS

For a 7705 SAR chassis that is equipped with a GNSS receiver and an attached GNSS antenna, the GNSS receiver can be used as a synchronous timing source. GNSS data is used to provide network-independent frequency and ToD synchronization.

The gnss command specifies a GNSS receiver port as a synchronous timing source. The specific GNSS receiver port is identified by port-id and has an assigned priority-value (from 1 to 16).

CLI Syntax:

config>system>time
    gnss
        port port-id time-ref-priority priority-value

Example:

config>system>time# gnss
config>system>time>gnss# port 1/2/1 time-ref-priority 1
